The equator is an imaginary line that divides the Earth into the Northern Hemisphere and Southern Hemisphere. Its length is about 24,901.5 miles (40,075 kilometers). The line crosses the continents of South America and Africa, as well as a number of islands, and runs through 14 countries, including Ecuador, Columbia, Brazil, Gabon, São Tomé and Príncipe, Congo, Zaire, Uganda, Kenya, Somalia, and Indonesia. The location of this imaginary line is indicated in many areas, making it possible to stand with a foot in each hemisphere. The geographical areas surrounding it are known as the equatorial regions, and they have a particular type of climate.
